1965 Barracuda with 84 318

Pulled the head: flat with no obvious cracks. head gasket perfect. block surface looks good, no cracks. SOMEHOW....water getting into that oil passage to tower.
The LONG head bolt at the oiling rocker shaft tower had water wet threads. Now I'm thinking - - maybe the threads are pulled or cracked in the block alllowing coolant to walk up the bolt into the oil passage????

I dunno.........
